It has just one target, but it has a large number of macros, and this number will grow exponentially with the number of options we add. I'd rather have an approach where the Makefile doesn't grow exponentially with the number of options.
I think that would mean replacing the 'REDO' macro with separate macros to control whether the main set of data is 'posix' or 'right', whether the second (opposite) set of data is to be made available, and whether the 'backzone' data is to be incorporated. Something along the lines of the attached Makefile? (I can convert this to a patch if required, but want to see what you think first.) One thing I'm not too sure of is the portability of macro expansions such as $(TZDIR_$(SET1)) which might make this a non-starter! -- -=( Ian Abbott @ MEV Ltd.
